Answer:
Increasing porosity and increasing permeability lead to increased production in an aquifer.
Explanation:
An aquifer is a body of rock / sediment that holds groundwater.
Porosity affects the amount of water a particular rock type can hold and depends on a couple of different factors such as how water circulates within the soil or ground.
The ability of the ground water to pass through the pore spaces in the rock is described as the rock's permeability.
Therefore, Increasing porosity and permeability will lead to increased production in an aquifer.

The image shows a ship using sonar to locate a school of fish. Which data are used to determine the distance of the ship from the fish?
A. The amount of time it takes the sound waves to travel to the fish and back to the boat
B. The number of sound waves the ship emits
C. The amount of time it takes the sound waves to travel from the boat to the fish
D. The number of sound waves that bounce off the fish
Answer:
A
Explanation:
The distance of the object that reflected the sound wave can be calculated by knowing the speed of sound in water and the time interval between transmission and reception of ultrasound.20 Mar 2017
which option do you think could cause near sightedness?
a) the eye lens doesn't refract light
b)the eye lens is concave
c)the eyeball is too long
D)the retina cells aren't reactive to light
Answer:A
Explanation:because it doesn’t refract light so you can’t see close
Answer:
A) the eye lens doesn't refract light
Explanation: because the eye doesn’t refract, or bend, light properly to focus on the retina. Makes eyesight appear blurry and distorted.

A rubber ball rolls across a flat floor. After 1 second, it has rolled 2 meters, and after 2 seconds, it has rolled an additional 1.6 meters. From this data, it is clear that the rolling ball has decreased in
Answer:
It has decreased in speed.
Explanation:
The second time it rolled, it had more time and did not go as far. Meaning it gained friction and decreased in speed.

Why are Sea Otters considered a keystone species?
Answer:
Sea otters are considered a "keystone species" because they can exert top-down pressure via predation on sea urchins, which are grazers upon kelp.Explanation:
As urchin density decreases from sea otter predation, so does the grazing pressure on kelp and as a result kelp forests flourish in the presence of sea otters.

A student wants to design an investigation to determine if an object has potential energy. What are some questions the student could ask to determine if the object contains potential energy? (Select 2)
Does the object have kinetic energy?
Does the object move when it is released from a rest position?
Does work have to be done to hold the object in place?
Does a force act on an object?
Is the object part of a system?
(i had another attempt, and 2 and 5 were innocent)
Response... Option 1 & 4
True or False
If two unbalanced forces act on an object in opposite directions, the object will move in the direction that the stronger force is acting.
Answer:
true
Explanation:
If two unbalanced forces act on an object in opposite directions, the object will move in the direction that the stronger force is acting. If two forces act in the same direction on an object, the forces add together and the object experiences a greater force in that direction

explain why the rocket can move at constant speed in outer space.
Answer:
When the rocket's engines are fired up, the force of gravity is disturbed, and the rocket takes off in the air. Later, as the rocket's fuel runs out, it slows down, comes to a halt, and eventually plummets to Earth's surface. Forces can affect objects in space as well. Spaceships are constantly in motion while traversing the solar system.
Explanation:
Please read!
Answer:
Explanation:
The rocket works because of the law of conservation of linear momentum. The law of conservation of linear momentum is very important in physics. Momentum is defined as the mass of an object times its velocity.
